    initial v1  
    11A little update on the issue.
    2 I've been struggling trying to workaround the problem and it seems that 90% of cases I managed to resolve using ST_MapAlgebraExpr and incrementally merging rasters in a loop. It is extremely slow but at least I managed to process some of the data (not sure whether it workaround all of the problems).

    44Another issue (or maybe a clue) I've found processing data obtained from a rasterized vector layer using ST_AsRaster. For some of pieces of data ST_Union works fine but in some cases fails, below you can find the piece of code that is failing due to lack of alignment  :
